ARTHUR IB. WRIGHT, OF HINSDALE, ILLINOIS.

RADIATION-REGULATOR.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed December 14, 1912. Serial No. 736,732.

To all whom it may concern Be it known that I, ARTHUR B. WRIGHT, a citizen of the United States, and a resident of the city of Hinsdale, in the county of Dupage and State of Illinois, have invented certain new and useful Improvements in Radiation-Regulators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, andthe numerals of reference marked thereon, which form a part of this specification.

Theradiators provided for cooling internal combustion engines, and more particularly for automobiles, have heretofore presented-the same surface for radiation independently of variation in weather conditions, notwithstanding that the amount of radiating surface required in winter is very small as compared with that required during the summer months in most localities, Attempts are frequently made to reduce the radiator surface in cold weather by securing a sheet of paper over the radiator to reduce the space for the admission of air therethrough. This has not proven satis factory, inasmuch as it is impossible by such means to properly adjust the radiating surface to the requirements of the engine. It frequently happens also during summer weather that the performance of such an engine is seriously affected on cool days when more or less motor difficulty is occasioned which might be easily avoided if the radiating surface could be quickly and satis-, factorily adjusted to the proper requirements of the engine.

The object of this invention is to provide a device adapted for use in connection with a radiator whereby the radiator surface may be increased to its maximum, or adjusted to any required amount less than maximum when desired, and maintain its adjustment under all conditions until again adjusted by the operator.

It is a further object of the invention to afiord a construction for regulating the draft of air through radiators to suit the requirements of weather conditions.

It is also an object of the invention to afford a construction admirably adapted to permit attachment of a distinguishing'sign, character, number or symbol on the front of the radiator.

it is an important object of my invention to aflord a construction whereby the radiation will be shown upon a suitable scale,

in front elevation. Fig. (Sis a fragmentary front elevation illustrating the attachment of a monogram, number plate or other sign or device upon the regulating means. Fig. 7 is an enlarged, fragmentary, front elevation of the regulating means. Fig. 8 is a fragmentary section taken on line 8--8 of Fig. 5. Fig. 9 is a fragmentary section taken on line 9-9 of Fig. 6. Fig. 10 is a fragmentary section on line 10l0 of Fig. 6.

As shown in the drawings: 1, indicates the radiator, which may be of any preferred or suitable kind, constructed in cellular form or pipes, as preferred, the same communicating at the top and bottom and sides, in the usual reservoir to enable the device to hold a suiiicient quantity of water, and being provided with a supporting frame 2 for the radiator, as shown. Said surrounding frame is extended forwardly from the reservoir proper to afford a space between the front thereof and the radiating surfaces for the installation of the regulator, and secured within the frame thus afi'orded at the top thereof, is a guide cleat 3, and at the bottom a guide cleat 4, shown as metallic angle bars rigidly bolted .or otherwise secured to the front plate 5, of

said frame. Also rigidly bolted to said front plate at the top and bottom thereof, is a grid 6, constructedof sheet metal or any suitable material, and which may comprise relatively thin bars arranged in parallel relation,as shown, and at a sufficient distance apart to permit a draft of air therethrough sufiicient for the maximum requirements for the radiator, though, of course, if desired, any fanciful or ornamental configuration for said grid may be employed consistent with permitting the requisite draft of air therethrough.

Mounted to slide between the cleats 3 and ment inone direction to close or partlyclose the openings through the grid 6, and in the other direction to permit unobstructed flow therethrough. Said grid 7, is of less width than the outer grid 6, and rigidly secured at" each side thereof, are outwardly directed threaded bolts 8, which extend through the lateral walls ofthe radiator, and are rovided at the outer" end thereof with ad usting nuts 9, whereby said inner grid 7, may be adjusted laterally in either direction to permit full opening through said grids or to restrict the openings therethrough, as required.

As shown also, a bolt .10, having a head 11, affording an indicating finger, is inserted through horizontal slots in the outer frame plate 5, of the radiator, and in the bottom bar of the outer grid 6, as shown in Figs. 5 and 8, and is threaded at its inner end into the rear grid 7, and a scale indicated by Y, is marked in any suitable manner upon thebottom frame plate 5, of the radiator adjacent said indicating finger, to permit the operator to know by inspection, the relative adjustment of said grids. Inasmuch as said grids may be made of relatively thin and light material, means are provided for rigidly securing the grids together in their adjusted position at or near their middle, and for this purpose the number plate, the monogram, or any suitable'device or designating tablet, is utilized. As shown in the drawings, the monogram 13, is used, and, of course, if a number plate is used for this purpose, the body of the plate may be cut away to afford apertures for the air therethrough around the numbers. In either event, the front grid 6, as shown in Figs. 3 and 10, is provided with transverse Webs 14, integral with and connecting some of the bars thereof near the middle of the grid and horizontally slotted, and screws or bolts 15 are inserted throug the monogram or tablet and through said s otte'd apertures in the front grid and threaded into the rear grid, thereby firmly clamping the grids together at their middle. If desired, thumb screws may be used for this purpose, permitting quick manual release without necessitating the use of a tool. I

The operation is evident from the foregoing.

In warm weather, when maximum radiating efficiency with maximum radiation ciency not generally understood by the operators of such machines.

Of course, although I have shown the device installed within the radiator frame, it is to be understood that the same may be attached at the frontof the radiator in any suitable manner, and wholly outside the radiator frame, if desired, thus adapting the device for installation on water cooled engines of any and all kinds and description.

It should be understood that while I have shown a monogram attached to the regulating device, the use thereof is intended as merely illustrative, and that a monogram or a registration number or both may be used for this purpose, as preferred. I have shown do not purpose limiting myself otherwise than necessitated by the prior art, as numerous'details of construction may be varied without departing from the principles of my invention. I

I claim as my invention:

A register, comprising a frameya stationary grid vertically disposed in said frame, a pair of transverse parallel angular bars rigidly secured to the top and bottom on the inner side of said frame, an adjustable grid slidably mounted between said bars and coacting with said stationary grid to control the draft therethrough, a pair of outwardly directed bolt members connected at each side of said adjustable rid and extending loosely through the latera walls of the frame, and adjusting members movably mounted on said bolt members to shift said adjustable grid laterally in either direction to vary the draft therethrough.

In testimony whereof I have hereunto subscribed my name in the presence of two sub scribing witnesses.

ARTHUR B. WRIGHT.
